Rated 5 out of 5 by from love new studio 9 I had been using another brand of bleach for a long time. Then my amazing sales consultant came by with the L’Oreal educator Kari. We tried it out by adding a few pieces while her colored processed. For the amount of time it was in the hair, the amount of lift was incredible. My new go to!
